To all whom it may concern: j

.Be it known-that I, JOHNQW-JACKSON, a

citizen. ofthe United States, and residing at St. Louis, in the State ofMissouri,-haveinvented certain new and useful Improve ments' in SteamWashing-Machines, of which the following is a specification.

This invention relates to washing machines and more particularly towash1ng ma-- Another object is to provide a novel form of diaphragm orfalse bottom which will promote the circulation of the water and steamin the container or boiler as the clothes are being washed and boiled.

,Another object is to provide novel driving means for the plunger whichis so arranged on the cover of the container that the stress will betransmitted over a large area, sothatv the sheet metal cover willnotbreak at the points of support of the driving means.

Another object is to provide a novel form of plunger which willcoiiperate with the diaphragm to further promote the circulation of thewater and steam through the clothes, and agitate the clothes.

Further objects will appear from-the detail description'taken inconnection wlth the accompanying drawings, in whlchz Figure 1 is a frontelevation of a washing machine embodying this invention, Fig. 2

is a section on the line22 Fig. 1, Fig. 3 is an enlarged cross sectionthrough the cover.

showing the driving mechanism in elevation, Fi g. 4' is a plan view ofthe diaphragm,

Fig. 5 1s a-plan view of the plungerhead,

the plunger rod being shownin section,'and Fig. 6 is an enlarged section.on the line 6'6Fig.5. ;R ferring tothe accompanying drawm s 10designates a stove body WlllCh may e constructedvof'sheet metal andwhich has a bottom 11 connected by a ilange 13 with the stove body, and.12 designates'the test-for supporting the stove body. A casting 14formin the stove front supports the fire and as -pit doors 15 and 16respectively.

The stove is provided with the usual grate forated at its up or en 17and with a stove pipe connection 18. A. plate 19 having a flange 20 issecured to the stove body at a point a short distance below the top ofthe body by means of riv-' ets 21 extending through the stove body andthe flange. This plate therefore forms an upper wallwhich is sunk ashort distance below the top of the stove body so that the sides extenda short distance above the up- ,per wall.

A container or boiler 22 of sheet metal is adapted to rest on theplateorlwall 19 andwithin the side walls of the stove body and isprovided with acover 23hinged at 24: and having a latch25 for securingit in closedv position. A diaphragm 26 having an in- ,clined flange 27rests upon the bottom of the container so as to form a false bottomtherefor. The body of this diaphragm has a comparatively large centralperforation or aperture 28 and a series of (in this case four)comparatively laiglge perforations 29; ,The flange 27 is provide with alarge number of comparatively small perforations 30 extending entirelyaround the circumference of the'diaphragm. The diaphragm is made ofsheet metal and is provided with strengthening ribs 31. The diaphragmfits loosely in the container or boiler, and in order to hold it inposition the boiler is headed as shown at 32, the bead extendinginwardly a sufiicient distance so that when the edge of the flange snapspast it the diaphragm will be held looseily in position on the bottom ofthe boiler. a drain cook 55, and the stove body is provided with a slot56 receiving the shank of the cock and permitting removal of thecontainer from the stove body.

I The plunger 33 has a series of conical plunger heads'34. These plungerheads are preferably made of sheet metal and are secured to the plungerby means of rivets 35 as shown in Fig. 6.5 The edge of the plun-. gerhead is turned over as shown at 36,.so'

as to form a smooth edge which will not tear the clothes.,-The lungerhead is perg as shown at 37 the perforations inc .ining downwardly forthe purpose hereinafter'to be described;

.The plunger has a plun or red 38 which extends through a flange bushing39 secured on the inside of the cover, andthrough a guide 40 formedonthe yoke of a bracketAl mounted on the upper side of the cover. Therod 38 has a slot 42 which is engaged by a set screw; 4:3 seas toprevent the he container has 20 turned.

rodand the plunger from turning, and the rod is also provided with aknob or handle 44 so thatthe plunger maybe raised or lowered by hand.

- The bracket 41 has a bearing for a pinion 45 which has a crank pinconnection 46 with a pitman or link 47. The other end of the link isconnected with a sleeve 48 slidable upon the rod 38 and having aclamping screw 49 engaging the slot 42 in the rod.

. The sleeve 48 is thus prevented from turning on the rod and may beclamped in any suitableposition thereon. The,pinion 45 meshes with agear 50 of a larger diameter .15 mounted on a drive shaft 51 having atone end .a bearing in the bracket 41 an at its other end a bearing in abracket 52 mounted on the cover. This drive shaft 51 is provided with heoperation of the machine is' as fol- .lows: Rotation .of the shaft 51throughthe handle 53 will cause a reciprocation of the plunger, and inview of the fact that the gear 50 is of larger diameter than the gear 45the reciprocation of the plunger is rapid.

When the water inthe container or boilerbecomes heated the waterandsteam will flow and circulate down the outside walls,

down through the apertures 30' in the flange 2'(', and up through theapertures 28 and 29 in the diaphragm, as shown by the arrows inFig. 2.Such a circulation takes place when the plunger is stationary, c. e.,when the clothes are being boiled. When the plunger is reciprocated theplunger heads will act as pumps to draw and force the.

water back and forth through the clothes. As the plunger moves up thewater will be '40 drawn up through the apertures .28 and 29 and downthrough the apertures 30 so that the circulation will take place in thedirections of the arrows, Fig. 2. When the plunger moves downthe'direction df flow will be reversed. As these plunger heads move downon the clothes and the water covering the same, the water will splash upinto these heads and will be forced out of the apertures 37, and" sincethese apertures are. in-

clined downwardly the water will be thrown b forcibly on top of theclothes. As the plunger heads rise they will act by suction to .draw thewater upwardly through the clothes. It will therefore be. seen thatwhile 55 the plunger is operated the water is drawn back and forththrough the clothes to thoroughly clean the same, butwhile the clothesare boiling the water will circulate upwardly at the centeranddownwardly along the'sides. In order to adjust the plungers to anyamount of clothes-in the container, the sleeve 48 is loosened and the.plunger is dropped down on theclothes'. The parts ahandle 53 whereby itmaybe are now moved to the position shown in Figs. 1 and 3 with thecrank pin connection 46 on its lower dead center. The sleeve is nowclamped to the rod, and when so adjusted will be in efiective operativeposition. j

The invention thus accomplishes its objects. The water will be drawn,and circulated through the clothes both when the plunger is operatedand when at a stand still while boiling. A plunger head is posit'ionedabove each aperture 28, 29, in thediaphragm body. The ribs 31 alsodivide the diaphragm into a plurality of compartments, one below eachplunger head. This results in a uniform and efiicient circulation. Theconnection of the driving mechanism to. the cover is over a large areaso that these connections will not work or tear loose when When thecontainer or boiler is removed that the smoke will not escape into theroom.

the'machine 'isused for any length offtifneT from 1;l 1 e-St0V6 bodf'thestove is not leftoperrbutisclosed'bythe wall or plate 19 so The stovebody walls projecting above the plate 19 also operate to retain thecontainer in position during the operation of the washing means, whilethe drain cock will hold the container against turning. The stove bodymay then be used also for heating laundry irons and the Iik It isobvious that various changes may be made in details: of constructionwithin the scope of the claims without departing from this invention,and it is therefore to be understood that this invention is not to belimited to the specific construction shown and described.

Having thus described the invention what I tainer upwardly in the centerand downwardly at the sides andvice versa.

In testimony whereof 'I aflix my signature in thep'resence of twowitnesses.
